What It Is and How It Works
Ivermectin is an antiparasitic agent that belongs to the avermectin class of medications.

For humans, it is primarily prescribed for infections caused by specific types of roundworms and, in some cases, for topical treatment of head lice and rosacea.
Indications / Uses
Ivermectin is approved for the treatment of several parasitic infections, including:
- Onchocerciasis (river blindness)
- Strongyloidiasis of the intestinal tract
- Lice and rosacea (topical formulations)
While some discussions have explored its off-label use for other conditions, such applications should only be considered with the guidance of a healthcare provider.
Dosage Forms and Typical Dosing Considerations
Ivermectin is available in oral and topical forms. The oral tablet is commonly used for parasitic infections, while topical formulations are used for treating lice and rosacea:
- Oral tablets: Dosing is typically weight-based and dependent on the specific condition being treated.
- Topical formulations: Applied to affected areas as directed for lice or skin conditions.
Dosing considerations should take into account age, weight, liver and kidney function, and any concurrent medications.
